IMPROVEMENT 1N AXLES lFOR VBHIGLES.

To ALL w'noM m1 MAY eoNenRN:-

Be it known that I, WILLIAM KNOCH, of Allegheny City, in the county .ofAllegheny, and State of Pennsylvania, have invented anew and usefulImprovement in Axlcsvfor Vehicles; and I do herehy declare that the i' ifollowingis a full, clear, and exact description thereof, which willenable those skilled in theart to 'malreand use the same, referencebeing had to the accompanying drawings, forming part of thisspecieation, in which- Figure 1 represents an end view of' my invention.i f

Figure 2 is a vertical longitudinal sectional view of the same.

Siniilar letters of reference indicate corresponding parts, A

This invention relates to anew manner of arranging the spindles aroundwagon-axles so that the hub can .i be easily` oiled, and that thespindle can be easily replaced whcndesired. I

The invention consists in fitting the spindle eccentric around. the axleso as to form a chamber above the axle, in which packing or grease is tobe placed, which will, as the wheel revolves, flow through small holesprovided in the under side of the spindle. i

A represents the squared end of the axle; 'B isthe metal spindle,`round, and tapering toward the front. The hole in the front endot' thespindle is in the centre of the same, while in its inner -end the holeis as far down as possible. Thus, the under side of the spindle isparallel with and close to the underside of the axle.' By a. nut, a, thespindle is fastened to the axle, as is clearly shown in lig. 2. Theroomabove the axle, between the same and the spindle, is tohe lled withgrease or'other lubricating-matter. b b are holes forlned in the underside of the spindle for the oil to ooze ont, and c is alhole arrangediin the inner head of the spindle'for the oil to he poured in. The hubis itted around the spindle, and is held in place by a. nut, which isfitted over a. serewthread',.d, that is provided on the front end ofthe'spindle, as shown in fig. 2. When the wagon stands still, its weightwill rest uponthe under side ot" the hub, and the holes b b will becompletely closed. 'As 'soon as the, wheels are turned there will beenough chances, during the jerks and shocks of the wagon for the oil to`llow out of the spindle and lubricate the hub. When a spindle is usedup,it canbe easily replaced.

I claim as new, and desire'to secure by Letters Patent- The taperingspindle B, constructed as described, fitting eccentrically uponthesquare shank of the axle,

the hole in the front end ofsaid spindle being in its'centre, andtheholo in the inner end placed near the lower edge, in suchv a mannerthat the under side of the axle lies parallel with the'lower perforatedsideot` the spindle, and an inclined lubricating-chamber formed abovethe axle, as .herein described for the purpose specified.
